Hi. My girlfriend is feeling a bit tired after having sex and has pain in her body. She was giving me oral sex and her mouth was full with saliva. With the flow, she took the saliva and rubbed it on her vagina. I started fingering her and realised that is it safe to do so. I am pretty sure I did not ejaculate in her mouth but there was definitely some pre cum. So we were thinking of taking a unwanted 72 medicine Will this be right to do so. Extra info: I am 20 she is 19 Her periods are due this coming thursday We want to avoid any chances of her getting pregnant but I do not want that she should harm herself in any way. Please respond.
